How to check 3PAR StoreServ system health

On a day to day basis, the most common thing which system administrators do is to check on every storage array is its system health, to determine whether the array is in good shape or working with a partially failed or fully failed component.
Most of the storage system administrators face issues with such task as they have to depend lot many software to get a clear idea of what is happening with the system,

In this article we will explore the possibilities of checking 3PAR StoreServ system health using native commands and its different options.

We use 2 commands quite often to determine the health of the system and they are checkhealth and showalert 
While checkhealth  command checks the status of different hardware components and reports the status,  showalert  displays system alerts.

showalert  when used with no options, only new alerts will be displayed. -all  will display all alerts irrespective of the the category whether it is service alert or general notification

mylab3par cli% showalert
Id          : 6
State       : New
Message Code: 0x02b00fa
Time        : 2016-07-01 14:10:06 EDT
Severity    : Major
Type        : Component state change
Message     : Cage 4, Power Supply 1 Failed (Power Supply Failed {0x402}).
 
 in this example, when used it no options, showalert  displayed only the new/latest alert which not acknowledged yet.

checkhealth  when used with no options, a thorough check(-svc) is performed. The most common options used along with checkhealth  are as follows,

detail :Will display detailed information regarding the status of the system.

-full :Will perform the maximum health check.

Once check is completed, it will show you the current status and its description.
